APPARATUS FOR TANNING.

Specification of Letters Patent No. 30,598, dated November 6, 1860.

T o all whom it may concern:

Be it known that I, JESSE S. IVHEAT, of IVheeIing, in the county of Ohio and State of Virginia, have invented a new and useful Improvement in Tanning Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanylng drawings, forming a part of this speci fication, in which- Figure l, represents a front View; F ig. 2, a vertical section, and Fig. 3, a horizontal section of the apparatus.

Similar letters of reference, in each of the several figures, indicate corresponding parts.

The nature of my invention consists, lst, in the relative arrangement of t-he suction pipes, force pump, supply pipes, communication pipes, escape valve exit pipes and emptying pipes, in combination with reservoirs and vats for the double purpose of effecting a complete circulation of the tanning liquid, through all the vats and allowing either' of the vats to be shut off from the circulation going on through the other vats or to be emptied if desired.

In consists, 2d, in the frames in the vats in combination with two eccentrics and connecting rods, so arranged that all of the frames may vibrate simultaneously, or any one of them remain at rest if desired, while the others vibrate.

Io enable others, skilled in the art, to make and use my invention, I will proceed to describe its construction and operation.

The bark and liquor are contained in sep arate reservoirs E2, E3, Et, E5, provided with perforated false bottoms Y, so that only the pure liquid will be allowed to pass into the spaces below the false bottoms. One reservoir El, which is destined to receive the liquor from either of the tanning vats hereinafter to be described, has no false bottom; as no liquor' is to be prepared in this reservoir and consequently no bark is to be placed therein.

A suction pipe A, leading to a force pump C, connects with the spaces underneath the false bottoms of the reservoirs E2, E3, E4, E5, by means of branch pipes A1, and by another branch pipe A1, with the reservoir El.

A supply pipe D, leads from the force .pump and connects with the bottoms of the first two of four vats X1, X2, X3, X4, by means of two branch pipes D1, D1. The

top of vat X1, connects with the bottom of l vat X2, by means of a pipe D2, and with the bottom of vat X3, by means of a pipe F. The top of vat X2, communicates in a simi lar manner with the bottom of vat X2, by means of a p ipe D3, and with the bottom of vat X, by means of a pipe F1. The top of vat X2', connects with the bottom of vat X4, by means of a pipe F2, F3. The pipe F3, leads into a valve boX R1, provided with a weighted valve T2. The exit pipe D5, leads from the valve box R1, into the reservoirs El, E2, E3, Et, E5, by means of branch pipes D, D2, DS, D, D1. On emptying, pipe G, connects with the bottoms of all the vats by branch pipes G1, G2, G3, G4, and leads into the reservoir El.

The pump C, is provided with an influx and efiiuX valve T, and T1, and each one of the branch suction pipes, branch supply pipes, communication pipes-connecting the vats with each otherbranch efflux pipes and branch emptying pipes is provided with a stop cock.

From the above, it will be seen that when the emptying cocks are all closed and all the other cocks opened, a continuous circulation of the liquid will be obtained from the different reservoirs through all the vats by working the force pump. As soon as either of the reservoirs is filled, the stop cock of its efflux branch pipe is to be closed, and the liquor allowed to flow into the others. By leaving open the stop cock of the suction branch pipe of that reservoir, the liquor will soon be pumped out of it if it should be desirable to empty it for the purposes of cleaning, repairing, &c. By shutting up the stop cock of its suction branch pipe, as well as that of its eiiux branch pipe, all communication of that reservoir with the rest of the apparatus is cut off. If it should be desirable to isolate either of the vats from the circulation of liquor going on through the vats, it is only necessary to shut the stop cocks connecting it with the other vats and the supply pipe. The circulation will then go on through the other vats, as before. The liquor contained in a vat thus isolated, can be drawn off whenever desired, by opening the stop cock of its branch emptying pipe and thus allow the liquor to run off into reservoir E1. The hides can then be taken out of the vats and others placed therein. To admit of free acess for this purpose, the vats are provided with man holes O, from which the covers can be taken off when IleCeSSaI'y.

A weighted valve T2, serves'to keep the liquor constantly under a certain pressure corresponding with the weight put on.

Each of the vats contains a frame H, hung on two pivots H1, H2. The frames serve to support the hides and are caused to vibrate so as to keep the hides in constant motion. The pivots H1, pass through stufhng boxes and have at their outer ends leversK, K1, K2, K3, attached to them. Two eccentrics I, I, serve to communicate a vibrating motion to the frames H, in the following manner: The forked end of the connecting iod"'L1, of one ofthe eccentrics, straddles the pivot at the lower end of arm K, and the forked end of the other eccentric rod L, straddles the pivot at the upper end of lever K2. A rod L3, is hinged to the lower end of lever K, and its forked end straddles the pivot at the lower end of arm K1. A rod L2, is hinged at one end to the upper end of lever K, and its other end is forked and straddles a pivot at the upper end of lever K2. In similar manner, rods L5, and L5, connect the lower ends of levers K1, K2, and K2, K3, respectively, and a rod L, similar to rod L2, connects the upper ends of levers K1, K5.

Rods Q, Q1, Q2, Q5, are suspended from the frame of the machine and are provided with suitable hooks--as represented in Fig. 2, at Z-into which the forked ends of the rods L, L1, L2, L5, L4, L5, L5, may be placed when they are det-ached from the pivot which they straddle.

If all the levers are connected as above described, the revolutions of the eccentrics will impart a rocking motion to allthe levers and to the frames H. But yif it should be desired to stop the motion of one of the From the above description, it will be seen that a complete circulation of the tanning liquor through the reservoirs and vats and at the same time an incessant motion of the hide frames inthe vats are obtained the hides subjected to the amount'of pressure desired, and the communication of either of the vats or reservoirs with the other parts of the apparatus may be cut olf, and the motion of either of the hide frames may be stopped without interfering with the circulation through the other reservoirs and vats or with the motion of the other hide frames. The vats are constructed from or lined with any metal or material that will not tarnish with the tanning matter used. The reservoirs are constructed of wood, and any number of vats or reservoirs may be employed if connected as described.

This process is not confined to bark tannage alone, but any preparation used in tanning in a liquid state such as terra japonica, oil, &c., may be employed.

Vhat I claim as my invention and desire to secure by Letters Patent, is-

1. The relative arrangement of the suction pipes A, A1, force pump C, supply pipes D, D', communication pipes D2, D3, D4, F, F1, F2, F3, eXit pipes D5, D, D7, D2, D2, D10, and emptying pipes Gr, G1, G2, G3, Gr", in combination with reservoirs E, El, E2, E5, E4, E5, vats X1, X2, X5, Xt, and weighted valve T2, for the double purpose of eecting a complete circulation'of the tanning liquid and pressure upon the hides, through all the vats and allowing'any of the vats to be shut off from the circulation going on through the other vats and to be emptied if desired, substantially as set forth.

.2. The frames H, in the vats in combination with two eccentrics I, I, and connecting rods L, L1, L2, L5, L4, L5, so arranged that all of the frames may vibrate simultaneously, or any one of themremain at rest if desired,

while the others vibrate, substantially as set forth.
